8.	Long-Term Debt

We have a $200 million revolving credit facility (the “Facility”). The Facility was increased from $125 million to $200 million in the first quarter of 2016. The Facility may be further increased to $250 million based on the terms and subject to the conditions set forth in the agreement relating to the Facility (the “Credit Agreement”). The Facility is available for working capital and general corporate purposes, including acquisitions, stock repurchases and issuances of letters of credit. Our obligations under the Facility are secured by 65% of the stock of our captive insurance subsidiary and are guaranteed by all of our domestic subsidiaries. In January 2016, we had net borrowings of $104.4 million to fund a portion of the purchase price of our modified Dutch auction tender offer. In addition, as of December 31, 2016, we had an outstanding $1.0 million letter of credit issued under the Facility. As of December 31, 2016, our outstanding balance on the Facility was $104.4 million.

The Facility matures on February 6, 2020. Borrowings under the Facility bear interest at an alternate base rate or LIBOR, at our option, plus an applicable margin. Depending on our leverage ratio, the applicable margin varies (i) in the case of LIBOR loans, from 2.00% to 2.75% and (ii) in the case of alternate base rate loans, from 0.00% to 0.75%. The alternate base rate is the highest of (i) the prime rate most recently published in The Wall Street Journal, (ii) the federal funds rate plus 0.50% and (iii) the 30-day LIBOR rate plus 2.00%. We also pay an unused commitment fee on the average daily unused portion of the Facility at a rate of 0.25%. The average interest rate during 2016 was 2.33%. Interest expense and unused commitment fees are recorded in other income (expense).

The Facility contains both affirmative and negative covenants that we believe are customary for arrangements of this nature. Covenants include, but are not limited to, limitations on our ability to incur additional indebtedness, sell material assets, retire, redeem or otherwise reacquire our capital stock, acquire the capital stock or assets of another business, make investments and pay dividends. In addition, the Credit Agreement requires us to comply with financial covenants limiting our total funded debt, minimum interest coverage ratio and maximum leverage ratio. In December 2014, the Credit Agreement was amended to modify the interest coverage ratio covenant to exclude the impact of special dividends paid of $50.7 million. We were in compliance with all financial covenants under the Credit Agreement at December 31, 2016.
